Where business case, contract, and technical reality intersect.
Pre-financial-close advisory for BESS Developers, IPPs, Investors, and Lenders. Making sure your commercial assumptions, contractual terms, and technical parameters actually agree before signatures are committed.
Business case. Contract. Technical reality.
Rarely checked. Until now!
Most BESS due diligence happens in silos. Legal counsel drafts the contract, an independent engineer reviews the technical design, and a commercial team builds the model. But due to underlying complexities, key dependencies are often overlooked.
Legal
Drafts and reviews the contract, warranty terms, conditions precedent.
Engineering
Reviews technical design, system and component performance, codes and standards.
Commercial
Builds the financial model, revenue stack, capex and opex assumptions, models returns.
Breaking down the silos.
I work at the intersection of all three, making sure a project's commercial assumptions, contractual terms, and technical parameters are mutually consistent before money and signatures are committed.
Business Case to Contract Alignment
A structured review of a supply, EPC, or services agreement against the financial model, flagging where they diverge and where hidden costs lie.
Contract vs Technical Reality Review
Evaluating whether the contract accurately reflects the technical complexities and limitations of the system. Ensuring nothing critical gets lost in translation between engineering and legal.
Technical Impact on Business Case
Translating technical limitations into their commercial impact. Stress testing if your financial model holds up against what the system can actually deliver.
Negotiation Support
Sitting directly alongside your team during contract negotiation, helping you navigate the underlying technical and commercial complexities at the table.
5 years inside a leading BESS OEM.
I'm Bernhard Schlagbauer. For 5 years I worked as a Sales Engineer at Fluence Energy on battery energy storage systems, from the development phase through to contracting and Notice to Proceed.
That gave me a rare combination: Deep technical BESS knowledge in system design, performance parameters, scope due diligence. Alongside direct experience negotiating and closing large, complex contracts. I know how suppliers think and where they build in flexibility and contingency, because I used to sit on that side of the table.
